Abstract
A synapse circuit to perform spike timing dependent plasticity (STDP) operation is provided. The synapse circuit includes a memristor having a resistance value, a transistor connected to the memristor, and the transistor configured to receive at least two input signals. The resistance value of the memristor is changed based on a time difference between the at least two input signals received by the transistor.
